glock barrels!

I am switching the barrel in my EDC Gen4 G19 from the Barsto to an S3F Solutions threaded barrel. Yes I am waiting on a 9mm suppressor to clear, but until it does I'll be working with this barrel. Expect a review of the Barsto eventually since I put around 10k rounds through it since I've carried it. The Barsto is going into a Gen3 G19 I have with Defoor sights to see how accurate I can get the gun with those sights.
